Overview
- Chief Justice John Roberts wrote that the president needed clear congressional authorization to levy sweeping import taxes under IEEPA, with Justices Neil Gorsuch and Amy Coney Barrett joining the majority.
- President Trump denounced the decision at the White House, calling some justices unpatriotic and disloyal, saying he was ashamed of them, and alleging—without evidence—that foreign interests influenced the Court.
- Trump said he will invoke Section 122 of the Trade Act to impose a 10% global tariff and pursue other tools such as Sections 232 and 301, though Section 122 is capped at 15% and roughly 150 days without congressional approval.
- The decision does not void all duties; sector‑specific and national‑security tariffs remain in effect, while challenges and guidance on refunds for IEEPA‑based levies loom.
- Economists and federal data indicate more than $130 billion to an estimated $175 billion was collected under the struck‑down tariffs, raising complex repayment exposure as business litigation accelerates.
